The Goryeo Palace Manwoldae Building Site No. 1-1 has a unique floor plan in which the main building and the buildings on both sides are arranged on the same axis, and the independent annex is built at right angles on the same foundation. Judging from this floor plan, the overall layout of Building Site No. 1-1 is likely to have been a structure in which the independent main and side buildings are arranged on the same axis and side building and annex are perpendicular to each other and their roof structures overlap. The structure of independent gable roofs on one axis was commonly seen in prestigious buildings such as palaces, temporary palaces, and buildings commemorating the king in local government offices during the Goryeo Dynasty, and traces of it can also be found in a few buildings in the central and local area during the early Joseon Dynasty. Meanwhile, the structure of two independent gable roofs overlapping at right angles was confirmed in government offices, local national and private schools, and housing construction from the late Goryeo Dynasty to the early Joseon Dynasty, suggesting that this architectural method was widely adopted. The structure of Building 1-1, graphically restored in this paper, is a meaningful relic that shows the architectural ideas of the Goryeo Dynasty's architectural structure and traces remaining in the Joseon Dynasty.

Dynasty and Japanese colonial period using historical texts and dictionaries. For Mat-bae roofs, component-related terms include Bak-gong, Bak-poong, Poong-pan, and Poong-cha, while Bae-jip refers to the roof as a whole. Bak-gong was more commonly used than its synonym Bak-poong, and its Chinese character representation varied. Poong-pan, derived from Pung-cha, replaced it in the 19th century, while Bae-jip’s use in Joseon-era texts is unclear. For Pal-jak roofs, component terms include Chu-nyeo and Hap-gak, while Paljak refers to the entire roof. Chu-nyeo has both linear and planar meanings and appeared with diverse Chinese character forms and Korean spellings, evolving over time. Hap-gak, synonymous with Heo-ga, became recognized as a native term until the 1940s. Pal-jak, often written as 八雀 in Joseon texts, likely originated from the Korean mimetic word Pal-jjak, reflecting its meaning and sound.

This study investigates how the spatial recognition structure is emerging through the case of rectangular plan combined with a combination of Dang-Sil(堂室) and Gong(工) shape roof, and identifies a type of architecture in the early Joseon Dynasty that has never been revealed. The conclusion of this study is as follows. First, the Dang and the Sil are connected to each other, but the architectural elements such as pillars, frame, and windows are distinguished and appear as separate buildings. Second, the distinction between Dang and Sil is evident by the difference in the number of ridges and the shape of the roof. In addition, the roof and roof framework of the independent rooms and the rooms were common in the right angled architecture where the direction and the expandability of each structure were maintained. Third, the construction of the Dang-Sil combined structure, in which two or more structure frameworks were combined with the rectangular combined flat roof structure, gradually changed into a single structure with a single ridge. Fourth, this change means that people of the early Joseon Dynasty recognized the Dang and Sil as separate architecture, but the strict sense of spatial separation has disappeared over time.

본 연구에서는 일반적인 지붕과 다른 형상을 갖고 있는 한옥의 지붕에 작용하는 풍압의 크기를 판단하고자 하였다. 한옥 지붕면에는 용마루, 내림마루와 추녀마루라는 특징적인 돌출부가 존재하는데, 건축구조기준에 제시된 풍압계수는 이러한 돌출부가 있는 지붕을 고려한 값은 아니기 때문에 구조기준에 근거하여 풍압계수를 결정하기에는 불확실한 요소가 존재한다. 이에 따라 본 연구에서는 한옥의 팔작지붕과 맞배지붕 중 마루 부분에 작용하는 풍압계수를 분석하였다. 풍동실험모델은 팔작지붕 1개와 맞배지붕 2개의 3종류를 제작하였다. 실험모델의 스케일은 애일당의 1/15 이다. 실험모델 풍압공은 팔작지붕의 경우, 지붕면 부분에에 1-198, 마루 부분에 199-243까지 총 243개의 풍압공을 배치하였다. 맞배지붕의 경우 지붕면 부분에 1-170, 마루 부분에 171-207까지 총 207개의 풍압공을 배치하였다. 풍동실험은 실험모델이 대칭인 점을 고려하여 0°에서 90°까지 수행하였다. 지붕면 가장자리에서 부압은 건축구조기준을 준수할 경우 문제가 없지만 추녀마루 끝단 부분에서는 문제가 있을 수 있음이 확인 되었다.
